Seamless pipes are one of the main elements in the construction of production and building communication systems. Due to the lack of seams in the design of such parts, we can say that they are one of the most durable of its kind. As practice shows, seamless pipes are really characterized by increased resistance to physical and mechanical influences, and therefore have high performance characteristics.
Application area
As we have already noted, these parts are distinguished by high operational characteristics. It is because of these qualities that they are used in those facilities where greater reliability is required. For example, thick-walled models of these devices are used when laying water and gas pipelines. Hot rolled seamless pipes are widely used in the oil and gas industry and engineering. In addition, such products are used in public utilities. It is also worth noting that most of the products produced in the territory of the CIS countries (including seamless pipe GOST 8732-78 including) are imported for many countries in Europe.
Varieties
According to the wall thickness, these products are divided into two types:
- Thick-walled.
- Thin-walled.
The width of the walls of the first type of parts varies from 12.5 to 40.0 millimeters. A thin-walled pipe - seamless cold-deformed - has a wall width of 6 to 12.5 millimeters.
According to the accuracy of manufacturing the diameter of these pipes can be divided into ordinary products and products of high accuracy. The length of the steel element itself can be from 4 to 12.5 or more meters.
Material
Often, seamless pipes are made of high-strength alloyed or carbon steel. Both materials are characterized by high reliability and performance. Thanks to this, seamless pipes are extremely resistant to corrosion, aggressive substances and other chemicals.
Depending on what type of steel was used in the design of the product, specialists distinguish several types of seamless pipes:
- With standardization of mechanical properties.
- With standardization of chemical composition.
- With the rationing of both (chemical and mechanical) characteristics.
- Without observing the properties and composition.
By the way, manufacturing methods
there are four of these parts. It can be: forging, rolling, pressing or drawing. However, no matter what method of manufacture is used, such products will always be as durable and resistant to external aggressive factors.
Conclusion
Thus, seamless pipes are one of the most durable and resistant products used in industrial and municipal communication systems. Such a wide range of applications is explained by the high performance characteristics of this product. And this, in turn, is a special seamless method of manufacturing and the use of the most durable grades of steel - alloyed and carbon.
